Change them, basically. I suggest the spring way, using sprites (images) to make the lasers look cooler, they also don't look like lasers in TA3D at the moment, they look dull. They need to be lighter rather than coloured stretched blobs. I made an example of what I mean with two of my own home made lasers in photoshop. Is there a way to make this happen?

It could be done using a texture with alpha channel which can be repeated indefinitely, eventually I can add a head and tail to the laser (let's say top/bottom of the texture or left/right). Since it has yet to be implemented, I let you chose what you think is more convenient.

Left and right would be convenient, by adding head and tail you mean another small image attached to each end correct? Easily enough done, and repeating the middle image would be great, this way you can choose how long it is by choosing how many times the image repeats, right?

I've implemented it (without head/tail textures yet). This is how it looks:

Textures can be replaced for each laser weapon. I am wondering if it would be better to have the texture including the head and tail directly and when the laser hits something the head is just not drawn (texture is just cut to current laser length), this would give you full control over the laser texture from your image editor. What do you think ?

I joins an image done in the Gimp (Photoshop is pretty bad with PNG transparency) : When TA3D use it (it's the ARM LLT shooting), the shoot is black. Transparency is transparent, but all the color of the laser is black.
